Wearable device, strap mechanism and connection component

Abstract

The present application provides a wearable device, a strap mechanism and a connection component. The wearable device includes a strap mechanism and a watch head mechanism. The strap mechanism includes a strap component and a connection component. The connection component includes a connection head connected to the strap component and an air guide member provided on the connection head and connected to the strap component. The connection head is assembled on the watch head mechanism and is detachably connected to the watch head mechanism. The air guide member has an air passage communicating with the strap component. When the connection head is assembled on the watch head mechanism, the air passage is synchronously connected to the watch head mechanism, and the watch head mechanism inflates and deflates the strap component through the air passage. Thus, the connection head can not only achieve the detachable connection between the strap component and the watch head mechanism, but also play a role in fixing the connection between the air passage and the watch head mechanism, so as to omit the structure required for fixing the air passage on the watch head mechanism, increase the available space of the watch head mechanism, and reduce the limitations brought to the design and layout of the watch head mechanism due to insufficient space.

Description

Technical Field

[0001] This application relates to the technical field of wearable devices, specifically to a wearable device, a strap mechanism, and a connection component. Background Technology

[0002] Currently, common blood pressure measurement solutions in smartwatches involve placing an air bladder on the watch band and inflating it via the watch head. This inflates the bladder to compress and block the user's blood vessels for blood pressure measurement. The air valve for the air bladder is typically located on the watch head, connecting to an internal air pump that inflates the bladder. The watch head also includes a retaining structure to secure the valve and improve the connection. However, this retaining structure generally occupies some space on the watch head, reducing usable space and limiting the watch's design and the layout of its internal components. Summary of the Invention

[0003] This application provides a wearable device, comprising: a watchband mechanism and a watch head mechanism, wherein the watchband mechanism includes: a watchband assembly and a connecting assembly; the connecting assembly includes: a connector connected to the watchband assembly, and an air guide disposed on the connector and connected to the watchband assembly; wherein the connector is configured to be mounted on the watch head mechanism and detachably connected to the watch head mechanism; the air guide has an air passage communicating with the watchband assembly; when the connector is mounted on the watch head mechanism, the air passage is synchronously connected to the watch head mechanism, and the watch head mechanism is configured to inflate and deflate the watchband assembly through the air passage.

[0004] In another aspect, this application provides a watch strap mechanism connected to a watch head mechanism. The watch strap mechanism includes a watch strap assembly and a connecting assembly. The connecting assembly includes a connector connected to the watch strap assembly and an air guide disposed on the connector and connected to the watch strap assembly. The connector is configured to be mounted on the watch head mechanism and detachably connected to it. The air guide has an air passage communicating with the watch strap assembly. When the connector is mounted on the watch head mechanism, the air passage is simultaneously connected to the watch head mechanism, and the watch head mechanism is configured to inflate or deflate the watch strap assembly through the air passage.

[0005] This application also provides a connecting component for connecting a watch strap assembly and a watch head mechanism. The connecting component includes: a connector connected to the watch strap assembly, and an air guide disposed on the connector and connected to the watch strap assembly; wherein the connector is configured to be inserted into the watch head mechanism and detachably connected to the watch head mechanism; the air guide has an air passage communicating with the watch strap assembly; when the connector is inserted into the watch head mechanism, the air guide is simultaneously inserted into the watch head mechanism so that the air passage communicates with the watch head mechanism, and the watch head mechanism is configured to inflate or deflate the watch strap assembly through the air passage.

[0006] The wearable device provided in this application features an air guide with an air passage on a connector that connects to the watch band assembly and is detachably connected to the watch head mechanism. When the connector is connected to the watch head mechanism, the air passage also connects the watch band assembly and the watch head mechanism. This allows the watch head mechanism to not only be detachably connected to the watch band assembly via the connector but also to inflate and deflate the watch band assembly via the air guide. This design allows the connector to simultaneously fix the air guide when detachably connected to the watch head mechanism, eliminating the need for a structure to fix the air guide (air passage) in the watch head mechanism. This increases the usable space in the watch head mechanism, reducing the limitations imposed by insufficient space on the watch head mechanism's design and internal component layout.

[0024] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be particularly noted that the following embodiments are for illustrative purposes only and do not limit the scope of the application. Similarly, the following embodiments are only some, not all, embodiments of the present application, and all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of the present application.

[0025] In this application, the reference to "embodiment" means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0026] Please see Figures 1 to 2 , Figure 1 This is a partial structural schematic diagram of the wearable device 10 provided in an embodiment of this application. Figure 2 yes Figure 1 A schematic diagram of the structure of the middle strap mechanism 100.

[0027] The wearable device 10 provided in this application can be a smartwatch, a smart bracelet, or a cuff-type blood pressure measuring device, etc. The following example uses a smartwatch as the wearable device 10. Figure 1 As shown, the wearable device 10 includes a strap mechanism 100 and a head unit 200. The strap mechanism 100 is detachably connected to the head unit 200 and can be used to form a wearing space for the user. The strap mechanism 100 can also expand or contract under the control of the head unit 200 to facilitate the measurement of the user's blood pressure. The head unit 200 can integrate various functional components required by the wearable device 10 and can be used to inflate or deflate the strap mechanism 100, allowing it to expand or contract under the control of the head unit 200. In this embodiment, when the watch strap mechanism 100 and the watch head mechanism 200 are detachably connected, the watch strap mechanism 100 can also be synchronously connected to the watch head mechanism 200, so that the structure for fixing the inflation / deflation interface of the watch strap mechanism 100 can be omitted from the watch head mechanism 200, thereby increasing the available space of the watch head mechanism 200 and reducing the limitations on the shape design and internal component layout of the watch head mechanism 200 due to insufficient space.

[0028] The watch strap mechanism 100 can be detachably connected to the watch head mechanism 200 and can expand or contract under the control of the watch head mechanism 200. For example... Figure 2As shown, the watch band mechanism 100 includes a watch band assembly 110 and a connecting assembly 120. The watch band assembly 110 is connected to the connecting assembly 120 and can be detachably connected to the meter head mechanism 200 via the connecting assembly 120. The watch band assembly 110 can also expand or contract under the control of the meter head mechanism 200 to cooperate with the meter head mechanism 200 in measuring the user's blood pressure. The connecting assembly 120 is connected to the watch band assembly 110 and can also be mounted on and detachably connected to the meter head mechanism 200, thus achieving a detachable connection between the watch band assembly 110 and the meter head mechanism 200. Simultaneously, when the connecting assembly 120 is assembled with the meter head mechanism 200, it can simultaneously connect the watch band assembly 110 and the meter head mechanism 200, allowing the meter head mechanism 200 to inflate or deflate the watch band assembly 110 via the connecting assembly 120, thereby achieving the expansion or contraction of the watch band assembly 110.

[0029] The inventors discovered that, in addition to a structure for detachable connection with the watch band assembly 110, the watch head mechanism 200 in the relevant solutions also includes a structure for securing the inflation / deflation port of the watch band assembly 110. For example, the watch head mechanism 200 has a groove for mounting the inflation / deflation port and a limiting cover for securing the inflation / deflation port within the groove. However, a separate structure for securing the inflation / deflation port (such as the aforementioned limiting cover) generally occupies a significant amount of space in the watch head mechanism 200, reducing its usable space and thus limiting the design and internal component layout of the watch head mechanism 200.

[0030] Based on this, the wearable device 10 provided in this application solves the above-mentioned technical problems by reusing the connecting component 120. That is, the watch head mechanism 200 can not only be detachably connected to the watch band assembly 110 through the connecting component 120, but also inflate and deflate the watch band assembly 110 through the connecting component 120. Compared with the scheme of using two different structures to realize detachable connection and fixed inflation / deflation interface respectively, the watch head mechanism 200 in this embodiment can omit the structure used to fix the inflation / deflation interface of the watch band assembly 110, so as to increase the available space of the watch head mechanism 200 and reduce the limitations on the shape design and internal component layout of the watch head mechanism 200 due to insufficient space.

[0031] All directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of this application are only used to explain the relative positional relationship and movement of the components in a specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products, or devices.

[0032] Please combine Figure 2 See Figures 3 to 5 , Figure 3 yes Figure 2 A schematic diagram of the connection structure between the middle part of the watch strap 111 and the connecting component 120. Figure 4 yes Figure 2 A partial structural diagram of the central airbag 112. Figure 5 yes Figure 1 A schematic diagram of the cross-sectional structure of the wearable device 10 along line V-V.

[0033] The watch strap assembly 110 is connected to the connecting assembly 120 and can expand or contract under the control of the watch head mechanism 200. For example... Figures 2 to 3 As shown, the watch band assembly 110 includes a watch band 111 and an air bladder 112. The watch band 111 is connected to a connecting assembly 120 and can be detachably connected to a watch head mechanism 200 via the connecting assembly 120. The watch band 111 can be used to form a wearing space for the user in conjunction with the watch head mechanism 200. The air bladder 112 is disposed on the watch band 111 and connected to the connecting assembly 120. The air bladder 112 is also in communication with the connecting assembly 120, allowing the watch head mechanism 200 to inflate and deflate the air bladder 112 via the connecting assembly 120 to control the expansion or contraction of the air bladder, thereby cooperating with the watch head mechanism 200 to measure the user's blood pressure. Of course, in addition to blood pressure measurement, the air bladder 112 can also cooperate with the watch head mechanism 200 to achieve other measurement functions (such as heart rate measurement), which is not limited in this embodiment.

[0034] For example, the end of the watch strap 111 is connected to the connecting component 120, and the connecting component 120 is preferably embedded in the end of the watch strap 111. This enhances the connection between the watch strap 111 and the connecting component 120 while also concealing the connecting component 120, thereby improving the aesthetic appearance of the watch strap mechanism 100. Simultaneously, a portion of the structure of the connecting component 120 can protrude from the watch strap 111 to allow for a detachable connection with the watch head mechanism 200. Furthermore, the side of the watch strap 111 within the wearing space can also be used to connect to the airbag 112, allowing the airbag 112 to fit snugly against the user's wrist, thus cooperating with the watch head mechanism 200 to measure the user's blood pressure. For instance, the side of the watch strap 111 within the wearing space has a connecting hole 1111, and the airbag 112 has a connecting post 1121 inserted into the connecting hole 1111 and press-fitted with the watch strap 111. Figure 4 (As shown), this allows for a detachable connection between the watch strap 111 and the airbag 112 (the positions of the connecting hole 1111 and the connecting post 1121 can also be interchanged). Alternatively, a Velcro closure can be provided on one side of the watch strap 111 within the wearing space, and this Velcro closure can be used for detachable connection with the airbag 112. In this embodiment, the material of the watch strap 111 can be TPU (Thermoplastic Urethane), knitted material, or fluororubber. Of course, the material of the watch strap 111 is not limited to these, and this embodiment does not list them all.

[0035] Optionally, the connecting component 120 can be embedded in the end of the watch strap 111, or it can be connected to the end of the watch strap 111 in other ways, as long as it can ensure that the watch strap 111 and the connecting component 120 have sufficient connection strength, and that the connecting component 120 can cooperate with the watch head mechanism 200. This embodiment is not limited in this respect. At the same time, in addition to being detachably connected to the airbag 112, the watch strap 111 can also be fixedly connected to the airbag 112, so that the watch strap 111 and the airbag 112 are not detachable, as long as it can ensure that the airbag 112 can communicate with the connecting component 120. This embodiment is not limited in this respect either.

[0036] Airbag 112 is located on one side of the watch strap 111 within the wearing space, and airbag 112 is also connected to and communicates with connecting component 120. For example... Figures 4 to 5As shown, the airbag 112 may include an airbag body 1122 and an air nozzle 1123. The airbag body 1122 is located on one side of the watch strap 111 within the wearing space and is connected to the watch strap 111. The airbag body 1122 may have the aforementioned connecting post 1121 on the side facing the watch strap 111. The air nozzle 1123 is located at the end of the airbag body 1122 on the side facing the watch strap 111, and is also connected to the interior of the airbag body 1122. Simultaneously, the air nozzle 1123 can also be connected to the connecting assembly 120, connecting the airbag body 1122 and the connecting assembly 120, allowing the watch head mechanism 200 to inflate or deflate the airbag body 1122 through the connecting assembly 120, thereby achieving the expansion or contraction of the airbag body 1122. In this embodiment, the air nozzle 1123 is preferably inserted into the connecting assembly 120 to communicate with it.

[0037] Optionally, to improve the airtightness of the airbag body 1122, the airbag body 1122 and the air nozzle 1123 can be fixed by heat pressing to improve the tightness of the connection between the airbag body 1122 and the air nozzle 1123. Of course, other connection methods can also be used for the airbag body 1122 and the air nozzle 1123, and this embodiment does not limit this.

[0038] Optionally, to reduce the probability of air leakage at the connection between the nozzle 1123 and the connecting assembly 120, the airbag 112 may also be provided with a sealing ring 1124 surrounding the nozzle 1123. When the nozzle 1123 is inserted into the connecting assembly 120, the sealing ring 1124 can abut against both the nozzle 1123 and the connecting assembly 120 to fill the gap between them, thereby reducing the probability of air leakage at the connection between the nozzle 1123 and the connecting assembly 120. In this embodiment, the sealing ring 1124 may be made of elastic materials such as silicone, rubber, and soft plastic, so that the sealing ring 1124 can abut against both the nozzle 1123 and the connecting assembly 120. Optionally, in addition to the sealing ring 1124, adhesive may also be applied to the connection between the nozzle 1123 and the connecting assembly 120 for sealing.

[0039] Optionally, the number of air nozzles 1123 can also be two, and the two air nozzles 1123 can be symmetrically arranged on the ends of the airbag body 1122 and used to insert into the connecting assembly 120 to connect the airbag body 1122 and the instrument head mechanism 200, so that the instrument head mechanism 200 can inflate and deflate the airbag body 1122 through the two air nozzles 1123. Of course, in addition to symmetrical arrangement, the two air nozzles 1123 can also be arranged according to design requirements, as long as the two air nozzles 1123 can be inserted into the connecting assembly 120 to realize the connection between the airbag body 1122 and the connecting assembly 120. This embodiment does not limit this.

[0040] Optionally, when there are two air nozzles 1123, the airbag body 1122 can have two independent cavities, and the two cavities can be connected to the two air nozzles 1123 respectively. When the user wears the wearable device 10, one cavity can cover most of the user's wrist, allowing the airbag body 1122 to expand significantly after inflation, tightly constricting the user's wrist and compressing blood vessels. The other cavity can cover the area where the radial artery is located in the user's wrist, allowing the airbag body 1122 to expand slightly after inflation, conforming to the arterial area of ​​the user's wrist. This, in conjunction with the meter mechanism 200, measures data such as the user's pulse pressure wave, ultimately realizing the blood pressure measurement function of the wearable device 10.

[0041] Optionally, in addition to the aforementioned airbag 112 structure, the specific structure of the airbag 112 can be adapted to meet design requirements, and this embodiment does not limit this. For example, the design of the air nozzle 1123 can be omitted, and a rigid structure for the connecting component 120 to be inserted can be provided on the airbag body 1122 to achieve communication between the airbag body 1122 and the connecting component 120. Alternatively, the airbag body 1122 itself can be directly inserted into the connecting component 120 to achieve communication between the airbag body 1122 and the connecting component 120. Or, the airbag body 1122 and the connecting component 120 can be an integral structure that is connected to each other to achieve communication between the airbag body 1122 and the connecting component 120, and this embodiment does not limit this.

[0042] Optionally, the airbag 112 may not be limited to being located on the side of the watch strap 111 facing the wearing space. For example, the airbag 112 may consist only of the airbag body 1122, which may be embedded within the watch strap 111 and communicate with the connecting component 120 within the watch strap 111. Meanwhile, considering the expansion of the airbag body 1122, the watch strap 111 is preferably made of a material that can deform with the expansion of the airbag body 1122, thereby reducing the restriction on the expansion of the airbag body 1122 by the watch strap 111. In this embodiment, the specific connection method between the airbag body 1122 and the connecting component 120 is the same as or similar to that in the above embodiments, and will not be described in detail here.

[0043] Please combine Figure 5 See Figures 6 to 8 , Figure 6 yes Figure 2 A schematic diagram of the structure of the middle connecting component 120. Figure 7 yes Figure 6 A schematic diagram of the structure of the middle connector 121. Figure 8 yes Figure 6 A structural schematic diagram of the middle connector 121 from another perspective.

[0044] The connecting component 120 is connected to the end of the watch strap 111 and is detachably mounted on the watch head mechanism. The connecting component 120 also connects the airbag body 1122 and the watch head mechanism 200, allowing the watch head mechanism 200 to inflate and deflate the airbag body 1122 via the connecting component 120. Figure 5 As shown, the connecting assembly 120 has an air passage 1201. When the connecting assembly 120 is detachably connected to the meter head mechanism 200, the air passage 1201 can simultaneously connect the airbag body 1122 and the meter head mechanism 200, allowing the meter head mechanism 200 to inflate or deflate the airbag body 1122 through the air passage 1201, thereby expanding or contracting the airbag body 1122. With this configuration, the connecting assembly 120 can fix the connection between the air passage 1201 and the meter head mechanism 200 through its detachable connection, allowing the meter head mechanism 200 to omit the structure required to fix the air passage 1201, thus increasing the available space in the meter head mechanism 200 and reducing the limitations imposed on the meter head mechanism 200's shape design and internal component layout due to insufficient space. The structure of the connecting assembly 120 will be described in detail below.

[0045] like Figures 5 to 8 As shown, the connecting assembly 120 includes a connector 121 and a sealing cap 122. The connector 121 is also embedded within the end of the watch strap 111, and a portion of the connector 121 protrudes beyond the watch strap 111, allowing it to be inserted into the watch head mechanism 200 for detachable connection. The connector 121 may also have the aforementioned air passage 1201, and when the connector 121 is inserted into the watch head mechanism 200, a portion of the air passage 1201 can also be inserted synchronously with the connector 121 into the watch head mechanism 200, with the insertion direction of the connector 121 parallel to the insertion direction of the air passage 1201. The sealing cap 122 is disposed on the connector 121 and is used to seal any openings left on the connector 121 due to the formation of the air passage 1201, ensuring the airtightness of the air passage 1201. In this embodiment, after assembly, the connector 121 and the sealing cap 122 can be embedded in the end of the watch strap 111 through in-mold injection molding. The connector 121 and the sealing cap 122 are preferably made of rigid plastic to provide structural strength to the connecting assembly 120 and to reduce its weight. Of course, the connection method between the connector 121 and the watch strap 111, as well as the materials used for the connector 121 and the sealing cap 122, can be adjusted according to design requirements; this embodiment does not limit these aspects.

[0046] Optionally, besides the connector 121 being inserted into the meter head mechanism 200, the connector 121 can also be inserted into the meter head mechanism 200 for detachable connection. Similarly, besides the air passage 1201 being inserted into the meter head mechanism 200, the air passage 1201 can also be inserted into the meter head mechanism 200 for communication. The following explanation will only take the example of the connector 121 being inserted into the meter head mechanism 200, and the air passage 1201 also being inserted into the meter head mechanism 200 simultaneously with the connector 121.

[0047] Understandably, connector 121 can be inserted into meter head mechanism 200 from the side of meter head mechanism 200. For example, the side of meter head mechanism 200 may be provided with an opening for partial or complete insertion of connector 121.

[0048] For example, the connector 121 can be the end link of the watch strap 111, and the connector 121 includes: a main body 1211, a conductive part 1212, a protrusion 1213, and a buckle part 1214. The main body 1211 can be embedded in the end of the watch strap 111 to achieve connection between the connector 121 and the watch strap 111. The conductive part 1212 is connected to the main body 1211 and protrudes from the watch strap 111, and the end of the conductive part 1212 away from the main body 1211 can also be inserted into the watch head mechanism 200. The protrusion 1213 is connected to the main body 1211 and passes through the watch strap 111. When the watch strap 111 and the watch head mechanism 200 cooperate to form a wearing space, the protrusion 1213 can also be exposed on the side of the watch strap 111 facing the wearing space for the air nozzle 1123 to be inserted. The buckle portion 1214 is connected to the side of the main body portion 1211 where the guide portion 1212 is provided, and protrudes from the end of the watch strap 111. The buckle portion 1214 can also be inserted into the watch head mechanism 200 for detachable connection. In this embodiment, the guide portion 1212 can be inserted into the watch head mechanism 200 simultaneously with the buckle portion 1214, and the insertion direction of the guide portion 1212 is parallel to the insertion direction of the buckle portion 1214. The main body portion 1211, the guide portion 1212, the protrusion 1213, and the sealing cover 122 can together form the aforementioned air passage 1201, so that the air passage 1201 can connect the airbag body 1122 and the watch head mechanism 200.

[0049] The main body 1211 may include a first side 1211a, a second side 1211b, and a third side 1211c. The first side 1211a connects the buckle 1214 and the guide 1212, and when the buckle 1214 is detachably connected to the watch head mechanism 200, the first side 1211a can also be positioned opposite to the watch head mechanism 200. The second side 1211b and the third side 1211c are both connected to the first side 1211a and positioned opposite each other. The second side 1211b is also positioned near the side of the watch strap 111 facing the wearing space and connects to the protrusion 1213, so that the protrusion 1213 is exposed on the side of the watch strap 111 facing the wearing space. The third side 1211c allows the processing part to process the main body 1211, and the third side 1211c may have an opening left due to the formation of the air passage 1201 during processing. The sealing cover 122 is provided on the third side 1211c and seals the opening left due to the formation of the air passage 1201 during processing.

[0050] The terms "first," "second," and "third" used in this application are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first," "second," or "third" may explicitly or implicitly include at least one of that feature.

[0051] The main body 1211 also has an air guiding space 1201a, and the inner wall of the air guiding space 1201a can be used to form the aforementioned air passage 1201 together with the guiding part 1212, the protrusion 1213 and the sealing cover 122. Figure 5 and Figures 7 to 8 As shown, the air guiding space 1201a can be connected to the through part 1212 on the first side 1211a, so as to be connected to the instrument head mechanism 200 through the through part 1212. At the same time, the air guiding space 1201a also has a first opening 1202a and a second opening 1202b formed on the second side 1211b and the third side 1211c, respectively. The first opening 1202a can be connected to the protrusion 1213 on the second side 1211b, so that the air guiding space 1201a can also be connected to the airbag body 1122 through the protrusion 1213 and the air nozzle 1123. The second opening 1202b is an opening left on the third side 1211c after the main body 1211 is machined to form the air guiding space 1201a, and the sealing cap 122 can be provided on the third side 1211c to seal the second opening 1202b. With the above configuration, the inner wall of the air guide space 1201a can be used together with the guide part 1212, the protrusion 1213 and the sealing cover 122 located on the side of the air guide space 1201a (hereinafter referred to as the sealing cover 122) to form the aforementioned air passage 1201.

[0052] Optionally, the first opening 1202a may not be limited to being located on the second side 1211b. For example, when the airbag body 1122 is located inside the watchband 111, the first opening 1202a may also be located on the third side 1211c, and the connecting end of the airbag body 1122 may extend to the third side 1211c to communicate with the air guiding space 1201a through the first opening 1202a. Of course, in addition to the third side 1211c, the first opening 1202a may also be located on any outer surface of the main body 1211, as long as the airbag body 1122 can communicate with the air guiding space 1201a through the first opening 1202a. This embodiment does not limit this.

[0053] Understandably, if the conductive part 1212 and the protrusion 1213 are connected by opening holes in the main body 1211 in their extending directions, the holes can only connect at the intersection in their extending directions. The area of ​​the main body 1211 corresponding to the intersection of the extending directions of the conductive part 1212 and the protrusion 1213 needs to have a sufficiently large thickness; otherwise, the holes opened by the conductive part 1212 and the protrusion 1213 in their extending directions will directly penetrate the main body 1211 and cannot connect within the main body 1211. Increasing the thickness of the main body 1211 will not only increase the weight of the connector 121 but also affect the thickness of the watch strap 111 (the main body 1211 is embedded in the watch strap 111), which is not conducive to the overall thin and light design of the watch strap mechanism 100.

[0054] Based on this, this embodiment, by creating an air-guiding space 1201a on the third side 1211c to connect the guiding portion 1212 and the protrusion 1213, can shorten the length of the holes created in the guiding portion 1212 and the protrusion 1213 in their extending direction, thereby reducing the required thickness of the main body 1211 at the connection point between the guiding portion 1212 and the protrusion 1213 (corresponding to the air-guiding space 1201a). Simultaneously, the design of the air-guiding space 1201a also facilitates subsequent processing of the air passage 1201's shape from the second opening 1202b. For example, the wall surface at the connection point between the air-guiding space 1201a and the guiding portion 1212 (the corner of the air passage 1201) can be polished from the second opening 1202b to grind sharp edges into curved surfaces, thereby improving the air-guiding effect of the air passage 1201.

[0055] Optionally, to prevent the sealing cap 122 from protruding on the third side 1211c due to blocking the second opening 1202b, a receiving groove 1203 can be provided on the third side 1211c, and the second opening 1202b can be formed on the bottom wall of the receiving groove 1203. The sealing cap 122 can be disposed within the receiving groove 1203 and block the second opening 1202b. The receiving groove 1203 can also absorb the thickness of the sealing cap 122 to prevent it from protruding on the third side 1211c. Simultaneously, the sealing cap 122 can be fixed in the receiving groove 1203 by adhesive application or spot welding to improve the connection strength and sealing performance between the sealing cap 122 and the main body 1211. In this embodiment, the shape of the sealing cap 122 can match the receiving groove 1203, and the size of the sealing cap 122 can be slightly smaller than the size of the receiving groove 1203 to facilitate installation of the sealing cap 122.

[0056] Optionally, the sealing cap 122 may also be spaced apart from the side wall of the receiving groove 1203, so that there is a gap between the sealing cap 122 and the side wall of the receiving groove 1203. With this configuration, when the watch strap 111 and the connector 121 are subjected to in-mold injection molding, the watch strap 111 can also fill the gap between the sealing cap 122 and the side wall of the receiving groove 1203, so as to further improve the bonding strength of the watch strap 111, the connector 121 and the sealing cap 122.

[0057] Optionally, the design of the sealing cap 122 can also be omitted. In this case, in order to form the aforementioned air guiding space 1201a without increasing the thickness of the main body 1211, the main body 1211 can also be designed as two independent structural components. The two independent structural components can be spliced ​​together to form a complete main body 1211, and can jointly enclose the air guiding space 1201a after splicing, thereby omitting the design of forming a second opening 1202b on the third side 1211c of the air guiding space 1201a. In addition, in order to improve the sealing performance of the air guiding space 1201a, the gap between the two spliced ​​structural components can be glued or filled with other airtight materials. In this embodiment, when the design of the sealing cap 122 is omitted, the inner wall of the air guiding space 1201a can be used to form the aforementioned air passage 1201 together with the guiding part 1212 and the protrusion 1213.

[0058] Optionally, the first side 1211a may also be recessed towards the main body 1211, forming a clearance space 1204 for avoiding the meter head mechanism 200, and both the connecting part 1212 and the latching part 1214 may be located within the clearance space 1204. When the latching part 1214 and the connecting part 1212 are simultaneously inserted into the meter head mechanism 200, the clearance space 1204 can be used to avoid interference with the meter head mechanism 200, thereby ensuring that the latching part 1214 and the connecting part 1212 can be inserted into place.

[0059] Optionally, the main body 1211 can also be bent toward the side of the strap 111 closer to the wearing space, so that the main body 1211 can have an arc curvature toward the wearing space, so that the end of the strap 111 in which the main body 1211 is embedded can be bent, thereby forming a wearing space together with the watch head mechanism 200. At the same time, the sealing cover 122 can also match the third side 1211c of the main body 1211. That is, the surface of the sealing cover 122 exposed on the third side 1211c can also be a curved surface, thereby avoiding the sealing cover 122 forming a protrusion on the third side 1211c. In addition, the thickness of the main body 1211 gradually decreases in the direction away from the conduction portion 1212, so that the thickness of the strap 111 can also gradually decrease in the direction away from the conduction portion 1212, which is beneficial to the thinner design of the strap 111. Of course, the shape of the main body 1211 is not limited, and the specific shape of the main body 1211 can be adapted to design requirements. This embodiment does not limit this.

[0060] The main body 1211 can also be bent in the direction of the third side 1211c near the second side 1211b, so that the main body 1211 can have a certain curvature to match the shape of the user's wrist, thereby reducing the gap between the user's wrist and the end of the watch strap 111 that connects to the main body 1211, which is beneficial to improving the tightness of the fit between the airbag body 1122 and the user's wrist after inflation.

[0061] Furthermore, the connecting part 1212 is connected to the first side 1211a and can be inserted into the meter mechanism 200 simultaneously when the latching part 1214 is inserted into the meter mechanism 200. The connecting part 1212 also has a vent hole 1201b that connects the vent space 1201a and the meter mechanism 200. The inner walls of the vent space 1201a and the vent hole 1201b can be used to form the aforementioned air passage 1201 together with the protrusion 1213 and the sealing cover 122. The axial direction of the vent hole 1201b can be parallel to the insertion direction of the connecting part 1212, and the vent hole 1201b can penetrate the connecting part 1212 on opposite sides near and away from the main body 1211, and simultaneously penetrate the first side 1211a of the main body 1211 to communicate with the vent space 1201a. With this configuration, the air vent 1201b can connect the air vent space 1201a and the meter mechanism 200 after the meter mechanism 200 is inserted into the end of the guide portion 1212 away from the main body portion 1211.

[0062] Optionally, to reduce the probability of air leakage at the connection between the conductive part 1212 and the meter mechanism 200, the connecting assembly 120 may also be provided with a sealing ring 123 sleeved on the conductive part 1212. Figure 5 and Figure 6 (As shown), when the conductive part 1212 is inserted into the meter mechanism 200, the sealing ring 123 can abut against both the conductive part 1212 and the meter mechanism 200 to fill the gap between them, thereby reducing the probability of air leakage at the connection between the conductive part 1212 and the meter mechanism 200. In this embodiment, the sealing ring 123 can also be made of elastic materials such as silicone, rubber, and soft plastic, so that the sealing ring 123 can abut against both the conductive part 1212 and the meter mechanism 200.

[0063] Alternatively, the vent 1201b may not be limited to the side of the through-conductor 1212 away from the main body 1211, and the vent 1201b may also penetrate the periphery of the through-conductor 1212, and the watch strap mechanism 100 may also communicate with the vent 1201b from the periphery of the through-conductor 1212.

[0064] Optionally, the design of the connecting part 1212 can be omitted. In this case, in order to achieve communication between the air guiding space 1201a and the meter mechanism 200, a third opening can be formed on the first side 1211a of the air guiding space 1201a. The meter mechanism 200 can be provided with a structure similar to the connecting part 1212, and the third opening can avoid the meter mechanism 200, so that the meter mechanism 200 can be inserted into the air guiding space 1201a through the third opening to achieve communication between the meter mechanism 200 and the air guiding space 1201a. In this embodiment, when the design of the connecting part 1212 is omitted, the inner wall of the air guiding space 1201a can be used to form the aforementioned air passage 1201 together with the protrusion 1213 and the sealing cover 122.

[0065] Furthermore, the protrusion 1213 is connected to the second side 1211b and passes through the watch strap 111, and the protrusion 1213 is also exposed on the side of the watch strap 111 facing the wearing space. At the same time, the protrusion 1213 can also be arranged around the first opening 1202a and surround a receiving hole 1201c that connects the air guiding space 1201a and the air nozzle 1123. The inner walls of the air guiding space 1201a, the air guiding hole 1201b and the receiving hole 1201c can be used together with the sealing cover 122 to form the aforementioned air passage 1201. Since the protrusion 1213 passes through the watch strap 111, the receiving hole 1201c can be exposed on the side of the watch strap 111 facing the wearing space for the air nozzle 1123 to be inserted. The sealing ring 1124 can abut against the inner walls of the air nozzle 1123 and the receiving hole 1201c respectively to improve the sealing performance of the air nozzle 1123 when inserted into the protrusion 1213. In this embodiment, the air nozzle 1123 and the protrusion 1213 can be detachably connected or non-detachably connected; this embodiment does not limit this.

[0066] Optionally, the aperture of the receiving hole 1201c can be larger than the aperture of the first opening 1202a, so that the air nozzle 1123 can still contact the second side 1211b after being inserted into the receiving hole 1201c, so as to limit the insertion distance of the air nozzle 1123 by using the second side 1211b.

[0067] Optionally, when the airbag 112 has a rigid structure on the airbag body 1122 into which the protrusion 1213 can be inserted, the protrusion 1213 can also be inserted into the rigid structure to connect the air guiding space 1201a and the airbag body 1122 via the receiving hole 1201c. Alternatively, the protrusion 1213 can also be directly inserted into the airbag body 1122 and fixedly connected to the airbag body 1122, so that the airbag body 1122 and the connector 121 are a connected integral structure.

[0068] Optionally, the protrusion 1213 can be omitted. In this case, to achieve communication between the air guide space 1201a and the instrument head mechanism 200, the nozzle 1123 can be directly inserted into the air guide space 1201a through the first opening 1202a to achieve communication between the airbag body 1122 and the air guide space 1201a. In this embodiment, when the protrusion 1213 is omitted, the inner wall of the air guide space 1201a can be used together with the inner wall of the air guide hole 1201b and the sealing cap 122 to form the aforementioned air passage 1201.

[0069] Optionally, the design of the connecting portion 1212 and the protrusion 1213 can also be omitted. In this case, the inner wall of the air guiding space 1201a and the sealing cover 122 can together form the aforementioned air passage 1201.

[0070] Optionally, when there are two air nozzles 1123, there can also be two air passages 1201, which are respectively connected to the two air nozzles 1123. Figures 5 to 8 As shown, the main body 1211 may have two independent air guiding spaces 1201a. There may also be two connecting parts 1212, each communicating with one of the two air guiding spaces 1201a, and each connecting part 1212 is also used to insert the meter mechanism 200. There may also be two protrusions 1213, each communicating with one of the two air guiding spaces 1201a, and each protrusion 1213 is also connected to one of the two air nozzles 1123. There may also be two sealing caps 122, and each sealing cap 122 is used to block the two second openings 1202b formed on the third side 1211c of the two air guiding spaces 1201a. In this embodiment, the two air guiding spaces 1201a, the two connecting parts 1212, the two protrusions 1213, and the two sealing caps 122 may be symmetrically arranged about the length direction L. The cooperation relationship between the individual air guiding space 1201a, the guiding part 1212, the protrusion 1213, and the sealing cover 122 can be referred to the aforementioned embodiments, and will not be repeated here.

[0071] Furthermore, the latching part 1214 is connected to the first side 1211a and is used to insert into the meter head mechanism 200 for detachable connection with the meter head mechanism 200. Figures 7 to 8As shown, the latching part 1214 may have a latching groove 12141. When the latching part 1214 is inserted into the meter head mechanism 200, the mating structure of the meter head mechanism 200 can enter the latching groove 12141 and engage with the latching part 1214 in the direction of exiting the meter head mechanism 200, thereby achieving a fixed connection between the latching part 1214 and the meter head mechanism 200. Simultaneously, the mating structure of the meter head mechanism 200 can also exit the latching groove 12141 to release the engagement with the latching part 1214, allowing the latching part 1214 to be detached from the meter head mechanism 200, thus achieving a detachable connection between the latching part 1214 and the meter head mechanism 200. In this embodiment, when there are two conductive parts 1212, the latching part 1214 is also located between the two spaced-apart conductive parts 1212.

[0072] Optionally, in addition to being detachably connected to the meter head mechanism 200, the latching part 1214 may also have the aforementioned air guide hole 1201b, so as to simultaneously connect with the meter head mechanism 200 when inserted. That is, the latching part 1214 can simultaneously serve the functions of detachably connecting with the meter head mechanism 200 and connecting with the meter head mechanism 200. In this embodiment, when the latching part 1214 has the air guide hole 1201b, the design of the connecting part 1212 can be omitted, and the way the air guide hole 1201b is opened on the latching part 1214 can be the same as or similar to the aforementioned embodiment, and will not be described in detail here.

[0073] Optionally, there can be two latching parts 1214, which are spaced apart between the two conducting parts 1212 and respectively inserted into the meter head mechanism 200 for detachable connection, thereby improving the connection stability between the connecting component 120 and the meter head mechanism 200. The two latching parts 1214 can also be symmetrically arranged to improve the consistency of their insertion into the meter head mechanism 200. Simultaneously, the slots 12141 on both latching parts 1214 can penetrate the sides of the two latching parts 1214 closest to each other, forming corresponding clearance positions between the two latching parts 1214, thus facilitating the entry of the mating structure of the meter head mechanism 200 into the slots 12141. Of course, the specific design of the slots 12141 can be adaptively adjusted according to requirements, as long as the mating structure of the meter head mechanism 200 can enter the slots 12141 and engage with the latching parts 1214; this embodiment does not limit this.

[0074] Please see Figures 9 to 13 , Figure 9 yes Figure 1 A schematic diagram of another section of the cross-sectional structure of the wearable device 10 along line V-V. Figure 10 yes Figure 9 A schematic diagram of the structure of the middle connecting component 120. Figure 11 yes Figure 10 A schematic diagram of the structure of the middle connector 121. Figure 12 yes Figure 10 Schematic diagram of the structure of the central air guide 124. Figure 13 yes Figure 10 A magnified view of a portion of point A in the middle.

[0075] Besides using connector 121 and sealing cap 122 to form air passage 1201, air passage 1201 can also be formed using other independent structural components. For example... Figures 9 to 10 As shown, the connecting assembly 120 provided in this embodiment may include a connector 121 and an air guide 124. The connector 121 can be connected to the end of the watch strap 111, and can also be mounted on and detachably connected to the watch head mechanism 200. The air guide 124 can be disposed on the connector 121, and the air guide 124 forms an air passage 1201 to connect the airbag body 1122 and the watch head mechanism 200 respectively when the connector 121 is connected to the watch head mechanism 200, thereby enabling the watch head mechanism 200 to inflate and deflate the airbag body 1122. With this configuration, the connecting component 120 can fix the connection between the air passage 1201 and the meter head mechanism 200 through a detachable connection, allowing the meter head mechanism 200 to omit the structure required to fix the air passage 1201, thereby increasing the available space of the meter head mechanism 200 and reducing the limitations on the shape design and internal component layout of the meter head mechanism 200 due to insufficient space. The structure of the connector 121 and the air guide 124 provided in this embodiment will be further described below.

[0076] like Figures 9 to 11 As shown, the connector 121 is inserted into the head unit 200 and detachably connected to it. The connector 121 may include a main body 1211 and a snap-fit ​​part 1214. The shape of the main body 1211 is the same as or similar to that of the previous embodiment, except that the main body 1211 provided in this embodiment does not have an air guide space 1201a, and the main body 1211 is only used for installing the air guide 124 and connecting to the watch strap 111. For example, the main body 1211 has a mounting groove 1205 that passes through the first side 1211a and the second side 1211b. The mounting groove 1205 can be used to install the air guide 124, and the air passage 1201 formed by the air guide 124 can communicate with the head unit 200 from the first side 1211a and with the airbag body 1122 from the second side 1211b. Furthermore, the shape of the latching part 1214 and its cooperation with the head mechanism 200 are the same as or similar to those in the aforementioned embodiments, and will not be described in detail here.

[0077] The air guide 124 is disposed within the mounting groove 1205, and when the connector 121 (snap-fit ​​part 1214) is inserted into the meter head mechanism 200, the air guide 124 can be simultaneously inserted into the meter head mechanism 200, so that the air passage 1201 is connected to the meter head mechanism 200. Figures 9 to 12 As shown, the air guide 124 includes an air guide tube 1241 and a fixing plate 1242. The air guide tube 1241 is disposed within the mounting groove 1205 and has an air passage 1201. The air guide tube 1241 also protrudes from a first side 1211a and a second side 1211b, respectively, to connect with the instrument head mechanism 200 and the airbag body 1122, thereby achieving communication between the air passage 1201 and the instrument head mechanism 200 and the airbag body 1122. The fixing plate 1242 is sleeved on the portion of the air guide tube 1241 protruding from the first side 1211a and is connected to the first side 1211a, and is used to fix the air guide tube 1241 within the mounting groove 1205. In this embodiment, the air duct 1241 can be made of plastic, and the fixing plate 1242 can be made of metal. The air duct 1241 and the fixing plate 1242 can be integrally manufactured using a metal insert injection molding process to improve the connection strength between the two. Of course, the air duct 1241 and the fixing plate 1242 can also be fixedly connected in other ways, as long as the fixing plate 1242 can effectively fix the air duct 1241.

[0078] For example, the air duct 1241 may include a first air duct 1241a and a second air duct 1241b. One end of the first air duct 1241a is located in the mounting groove 1205, while the other opposite end protrudes from the first side 1211a and is used to simultaneously insert the meter head mechanism 200 when the snap-fit ​​part 1214 is inserted into the meter head mechanism 200. The first air duct 1241a also has a first air outlet 1206a that communicates with the meter head mechanism 200. The first air outlet 1206a can also penetrate the side of the first air duct 1241a away from the second air duct 1241b. One end of the second air duct 1241b is connected to one end of the first air duct 1241a located in the mounting groove 1205, while the other opposite end protrudes from the second side 1211b and from the side of the strap 111 facing the wearing space, for insertion into the airbag body 1122. The second air duct 1241b also has a second air outlet 1206b connecting the first air outlet 1206a and the airbag body 1122. This second air outlet 1206b can penetrate the side of the second air duct 1241b away from the first air duct 1241a. In this embodiment, the inner walls of the first air outlet 1206a and the second air outlet 1206b form an air passage 1201 to connect the watch head mechanism 200 and the airbag body 1122, allowing the watch head mechanism 200 to inflate and deflate the airbag body 1122.

[0079] Optionally, the first air guide tube 1241a can be used not only for insertion into the meter head mechanism 200, but also for insertion into the meter head mechanism 200. That is, the meter head mechanism 200 can also be inserted into the first air outlet 1206a to achieve communication with the air passage 1201. At the same time, when the first air guide tube 1241a is inserted into the meter head mechanism 200, the first air guide tube 1241a may not protrude from the first side 1211a, but may only be located within the mounting groove 1205.

[0080] Optionally, the second air guide tube 1241b can be used not only for insertion into the airbag body 1122, but also for insertion into the airbag body 1122. That is, the airbag body 1122 can also be inserted into the second air outlet 1206b through the aforementioned air nozzle 1123 to achieve communication with the airway 1201. At the same time, when the second air guide tube 1241b is inserted into the air nozzle 1123, the second air guide tube 1241b may not protrude from the second side 1211b, but may only be located within the mounting groove 1205.

[0081] Optionally, when the second air guide tube 1241b is used to insert into the airbag body 1122, the design of the nozzle 1123 can be omitted, and the second air guide tube 1241b can play a similar role to the nozzle 1123, and be fixed to the airbag body 1122 by means of thermoforming or other methods. Meanwhile, during assembly, the airbag body 1122 can be connected to the second air guide tube 1241b first, and then the air guide component 124 with the airbag body 1122 can be installed into the mounting groove 1205.

[0082] Optionally, the axial directions of the first vent 1206a and the second vent 1206b intersect to form an included angle α greater than 90°. Figure 12 (As shown). Simultaneously, to facilitate the connection between the second air guide tube 1241b and the airbag body 1122, the end of the second air guide tube 1241b furthest from the first air guide tube 1241a can also be inserted through the thickness of the watchband 111. This allows the airbag body 1122, after communicating with the second air outlet 1206b via the air nozzle 1123, to fit more tightly onto the watchband 111, thereby facilitating the inflation of the airbag body 1122 and applying pressure to the user's wrist. Optionally, when the airbag body 1122 is embedded within the watchband 111, the second air guide tube 1241b can also be directly inserted into the airbag body 1122 without needing to be inserted through the watchband 111.

[0083] Optionally, a clearance groove 1211d communicating with the mounting groove 1205 is also provided on the third side 1211c, and the clearance groove 1211d is used to avoid the installation of the air guide pipe 1241, so as to avoid the air guide pipe 1241 interfering with the inner wall of the mounting groove 1205, which would cause the air guide pipe 1241 to be installed in place.

[0084] Furthermore, a fixing plate 1242 is disposed on the first side 1211a and sleeved on the portion of the first air guide tube 1241a that protrudes from the first side 1211a, and the fixing plate 1242 is used to fix the positions of the first air guide tube 1241a and the second air guide tube 1241b. Figure 9 , Figure 11 as well as Figure 13 As shown, a fixing groove 1207 is provided on the first side 1211a, and a mounting groove 1205 penetrates the bottom wall of the fixing groove 1207. This fixing groove 1207 can be used to install a fixing plate 1242 to improve the connection strength between the fixing plate 1242 and the main body 1211. In this embodiment, the fixing plate 1242 can be fixed in the fixing groove 1207 by means such as welding or threaded connection. Optionally, the design of the fixing groove 1207 can also be omitted.

[0085] Optionally, in order to further improve the connection between the fixing plate 1242 and the main body 1211, a positioning groove 1208 is also provided on the side wall of the fixing groove 1207, and the fixing plate 1242 is also provided with a positioning part 12421 protruding from the positioning groove 1208, so as to use the positioning part 12421 and the positioning groove 1208 to position the fixing plate 1242, thereby improving the connection between the fixing plate 1242 and the main body 1211.

[0086] Optionally, to further improve the connection between the fixing plate 1242 and the main body 1211, the first side 1211a may also be provided with a limiting groove 1209 communicating with the fixing groove 1207, and the limiting groove 1209 is also disposed opposite to the positioning groove 1208. At the same time, the fixing plate 1242 is also provided with a limiting part 12422 protruding into the limiting groove 1209, so as to use the limiting part 12422 and the limiting groove 1209 to limit the fixing plate 1242, thereby improving the connection between the fixing plate 1242 and the main body 1211.

[0087] Optionally, when the air guide tube 1241 and the fixing plate 1242 are integrally formed by injection molding with metal inserts, the periphery of the first air guide tube 1241a opposite to the first air outlet 1206a also has an annular protrusion 1241c, so as to increase the thickness of the first air guide tube 1241a by utilizing the annular protrusion 1241c. At the same time, the fixing plate 1242 can be sleeved on the side of the annular protrusion 1241c opposite to the first air guide tube 1241a, and is provided with a joint portion 12423 embedded in the annular protrusion 1241c and the first air guide tube 1241a. Figure 9(As shown), the connecting portion 12423 can also be bent and embedded within the annular protrusion 1241c and the first air guide tube 1241a to improve the connection strength between the air guide tube 1241 and the fixing plate 1242. In this embodiment, the number of connecting portions 12423 can also be multiple, so that the fixing plate 1242 can be firmly fitted onto the first air guide tube 1241a. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0088] Alternatively, the design of the fixing plate 1242 can be omitted, and the air duct 1241 can also be installed in the mounting groove 1205 in other detachable or non-detachable ways. For example, the air duct 1241 can be connected to the main body 1211 by means such as welding, bonding or snap-fit ​​to fix it in the mounting groove 1205.

[0089] Optionally, the air passages 1201 of the connecting assembly 120 provided in this embodiment can also be two. For example... Figures 10 to 11 As shown, the main body 1211 can have two mounting slots 1205, and the number of air guides 124 can be two, and the two air guides 124 can be installed in the two mounting slots 1205 respectively, so that the connecting assembly 120 can have two air passages 1201. The cooperation relationship between a single air guide 124 and the main body 1211 can be referred to the aforementioned embodiment, and will not be repeated here.

[0090] Optionally, when there are two air guides 124, the latching part 1214 can be located between the two spaced-apart first air guides 1241a. Furthermore, to match the meter mechanism 200, the area of ​​the first side 1211a located between the two first air guides 1241a can be recessed towards the main body 1211 to form a clearance space 1204. The latching part 1214 can be located within the clearance space 1204.

[0091] The connecting assembly 120 provided in this embodiment, by providing an air guide 124 with an air passage 1201 on the connector 121, and the air passage 1201 can also connect the airbag body 1122 and the watch head mechanism 200 when the connector 121 is connected to the watch strap 111 and the watch head mechanism 200 respectively, so that the connector 121 can also fix the connection between the air passage 1201 and the watch head mechanism 200 when it is detachably connected to the watch head mechanism 200. With this configuration, the structure required to fix the air passage 1201 in the watch head mechanism 200 can be omitted, thereby increasing the available space of the watch head mechanism 200 and reducing the limitations on the shape design and internal component layout of the watch head mechanism 200 due to insufficient space.

[0092] Please combine Figure 5 and Figure 9 See Figures 14 to 16, Figure 14 yes Figure 1 A structural diagram of the central header mechanism 200. Figure 15 yes Figure 14 A structural diagram of the unlocking component. Figure 16 yes Figure 1 A schematic diagram of a partial cross-sectional structure of the wearable device 10 along VII-VII.

[0093] The head mechanism 200 is detachably connected to the buckle part 1214, and the airbag body 1122 can be inflated or deflated through the air passage 1201, causing the airbag body 1122 to expand or contract. Figure 5 , Figure 9 as well as Figure 14 As shown, the head unit 200 includes a housing assembly 210, an air pump assembly 220, and an unlocking assembly 230. The housing assembly 210 can be used to install various functional components required by the wearable device 10 and is into which the latching part 1214 can be inserted. The air pump assembly 220 is located within the housing assembly 210 and communicates with the air passage 1201, and can inflate and deflate the airbag body 1122 through the air passage 1201. The unlocking assembly 230 is located on the housing assembly 210 and can enter the latching slot 12141 after the latching part 1214 is inserted into the housing assembly 210 to engage with the latching part 1214. The unlocking assembly 230 can also exit the latching slot 12141 to release the engagement with the latching part 1214, thereby achieving a detachable connection between the latching part 1214 and the head unit 200.

[0094] For example, the periphery of the housing assembly 210 is provided with a slot 211 into which the latching part 1214 can be inserted, and a portion of the unlocking component 230 is also located within the slot 211, so that the latching part 1214 can cooperate with the unlocking component 230 after being inserted into the slot 211. Simultaneously, the periphery of the housing assembly 210 is also provided with a passage part 1212 or a first air duct 1241a (…). Figure 5 and Figure 9 (As shown) the air hole 212 is inserted, and the air hole 212 is also connected to the air pump assembly 220, so that the guide part 1212 or the first air guide tube 1241a can be inserted into the air hole 212 simultaneously after the buckle part 1214 is inserted into the slot 211, so as to realize the connection between the air passage 1201 and the air pump assembly 220. In addition, the housing assembly 210 can also be used to cooperate with the watch strap 111 to form a wearing space, and the side of the housing 210 facing the wearing space can also have a sliding groove 213 connecting the slot 211. Figure 16(As shown), the slide groove 213 can accommodate the unlocking component 230 and is used to achieve a sliding connection between the unlocking component 230 and the housing component 210, allowing the unlocking component 230 to enter or exit the slot 12141. In this embodiment, when the conducting part 1212 or the first air guide tube 1241a is inserted into the air hole 212, the sealing ring 123 can abut against the inner wall of the air hole 212 to improve the airtightness at the location of the air hole 212.

[0095] Optionally, when there are two latching parts 1214, there are also two slots 211, for each latching part 1214 to be inserted into. When there are two air passages 1201, there are also two air holes 212, for each of the two guiding parts 1212 or the two first air guide tubes 1241a to be inserted into. In this embodiment, the housing assembly 210 has two slots 211 in the area between the two air holes 212.

[0096] The unlocking component 230 is located within the slide groove 213 and is slidably connected to the housing component 210. When the latching part 1214 is inserted into the slot 211, the unlocking component 230 can be pushed and displaced by the latching part 1214 to avoid its insertion. Simultaneously, after the latching part 1214 is fully inserted, the unlocking component 230 can also reset and engage with the latching part 12141. Furthermore, the unlocking component 230 can also be disengaged from the slot 12141 by user operation to release the engagement with the latching part 1214. This configuration allows the unlocking component 230 to achieve a detachable connection between the latching part 1214 and the meter mechanism 200. The structure of the unlocking component 230 will be further explained below.

[0097] like Figures 15 to 16As shown, the unlocking component 230 includes a slider 231 and an elastic member 232. The slider 231 is disposed within the slide groove 213 and can slide along the slide groove 213. When the latching part 1214 is inserted into the slot 211, the slider 231 can be pushed away by the latching part 1214 and can reset after the latching part 1214 is fully inserted, so as to engage with the latching part 1214 in the slot 12141. Simultaneously, the slider 231 is also exposed on the side of the housing component 210 facing the wearing space and can slide under the user's pressure to disengage from the slot 12141 and release the engagement with the latching part 1214. The elastic element 232 is disposed between the sliding element 231 and the bottom wall of the groove 213. When the sliding element 231 is pushed by the latching part 1214 or pressed by the user, the elastic element 232 can undergo elastic deformation under the pressure of the sliding element 231 to provide elastic force to drive the sliding element 231 to reset. It is understood that the structure of the aforementioned unlocking component 230 is only illustrative. In some embodiments, the structure of the unlocking component 230 may not be limited to this. It is only necessary that the unlocking component 230 can cooperate with the latching part 1214 to achieve a detachable connection. This embodiment does not limit this.

[0098] Optionally, the positions of the unlocking component 230 and the latching part 1214 can be interchanged. That is, the unlocking component 230 can be provided on the main body 1211, while the latching part 1214 can be provided on the housing component 210. With this configuration, the main body 1211 and the housing component 210 can still be detachably connected via the unlocking component 230 and the latching part 1214. The arrangement of the unlocking component 230 on the main body 1211 and the arrangement of the latching part 1214 on the housing component 210 can be the same as or similar to the aforementioned embodiments and will not be described in detail here.

[0099] Optionally, the unlocking component 230 and the latching part 1214 may not be detachably connected from the periphery of the housing component 210. For example, the top surface (such as the display surface) of the housing component 210 in contact with the periphery may have a mounting groove, and the bottom wall of the mounting groove may have the aforementioned slot 211 and vent 212. At the same time, the conducting part 1212 and the latching part 1214 may be provided on the second side 1211b of the main body part 1211. With this configuration, the main body part 1211 can be inserted into the mounting groove from the top surface, and the conducting part 1212 and the latching part 1214 can be inserted into the vent 212 and the slot 211 respectively, so as to detachably connect and communicate with the meter mechanism 200.

[0100] The wearable device 10 provided in this application has an air guide 124 with an air passage 1201 on a connector 121 that is connected to the watch band assembly 110 and detachably connected to the watch head mechanism 200. When the connector 121 is connected to the watch head mechanism 200, the air passage 1201 can also connect the watch band assembly 110 and the watch head mechanism 200. This allows the watch head mechanism 200 to not only be detachably connected to the watch band assembly 110 via the connector 121, but also to inflate and deflate the watch band assembly 110 via the air guide 124. With this configuration, when the connector 121 is detachably connected to the watch head mechanism 200, it can also simultaneously fix the air guide 124. This allows the watch head mechanism 200 to omit the structure used to fix the air guide 124, thereby increasing the available space of the watch head mechanism 200 and reducing the limitations on the shape design and internal component layout of the watch head mechanism 200 caused by insufficient space.
